    you know, i was looking at a 75 or so dodge 3/4 ton 2wed pickup that we were scrapping not too long ago and the box is a saginaw and identical in appearance to wehat GM trucks have and i bet it might work, as long as output splines are same and as long as input sdhaft is same length and everything, and also mounting bolt pattern four bolt holes too, im sure they are.

    get the casting number off the box housing and compare to the numbers on a gm one that would be a good start,

    Yeah I found one with a 4" drop pitman arm already on it, The guy said he knew it fit 73-87, so I figured it would work, as long as the fitting are the same, I will do some more research.

    The fittings are sae up until 1979 in 1980 the fittings went metric.

    The cases are the same for gm or dodge.

    becareful with some of the older dodge boxes IIRC
    74-76 were revese rotation.

    I'm not real sure about spline counts on the sector shafts but I do know that you can index the dodge pitman arm in 90* increments.

    I forgot one other important piece of info
    2wd and 4wd dodge boxes are the same. On the 2wd drive trucks the box mounts the frame the same was the gm's do. The 4x4 version uses a mounting plate to relocate the box further down on the frame. Because of the differnt mounting styles there are differnt pitman arms depending on how the box is mounted. Both pitman arms will interchange.

    You might also want to check and see where the rag joint on your vehicle is. The dodge rag joint is up on the column by the fire wall. iirc gm has it down by the gear box. I can count splines on an old dodge box I have laying around if you need that info

    The nice thing about the dodge box is the abilty to index the pitman arm every 90* so it will work with cross over steering.

    You could switch input shafts if you needed to. Or you could switch the sector shaft. I would probably switch input shafts its easier.
    and while your at it drill it for hydro

    BEWARE! The dodge steering and boxes use different tierods, I found this out the hard way buying a lifted steering arm and having to drill out the hole to fit my stock tierod. I thought about buying dodge tie rod ends but turns out they are usually special order and cost a good bit more, not to mention they are smaller in size (weaker) /forums/images/graemlins/eek.gif

    True the tie rod ends are different. He is not switching knuckles so the tie rod ends are not important. What is important is the diamater,taper and mounting direction of the pitman arm mounting hole that the drag link conects to. Since he is converting to crossover steering and using a dropped pitman arm the stock steering arm will not be used so it in not an issue either.

    sorry to say that the dodge knuckles are not drilled. But the knuckles are flat topped. Be warned that you will need to use dodge brakes to go with dodge spindles no way around that. imho the dodge brakes suck anyway the pistons in the calipers are too small. If you are having trouble finding flattop knuckles for your 10 bolt look at the fullsize jeep wagoneers 70's & 80's they use the flat top knuckles and the rest of the parts are the same. bearings spindles 6 lug hubs and all.
